主要思路
<template> <div class="container" id="content_box"> <div class="tab">左侧Tab</div> <div class="menu" ref="menu"> 左侧菜单 <div class="menu-resize" ref="menuResize"></div> </div> <div class="content"> 中心区域 <div class="opera" ref="opera"> <div class="opera-resize" ref="operaResize"></div> 操作区域 </div> </div> </div> </template> <script> export default { name: "dropWidth", mounted() { this.$nextTick(() => { this.dropSize(); }) }, methods: { dropSize() { let that = this, menuWidth = 200, operaHeight = 200; this.$refs.menuResize.onmousedown = function () { document.onmousemove = function (e) { let clientX = e.clientX; // 最大宽度 if(clientX>=330){ clientX = 330; } // 最小宽度 if(clientX<=230){ clientX = 230; } // TODO 这里减的是最左侧tab的宽度 menuWidth = clientX - 30; that.$refs.menu.style.width = clientX - 30 +"px"; } document.onmouseup = function () { console.log('当前宽度', menuWidth); document.onmousemove = null; document.onmouseup = null; that.releaseCapture && that.releaseCapture() } } this.$refs.operaResize.onmousedown = function () { document.onmousemove = function (e) { let clientY = e.clientY; console.log(clientY) // 最大宽度 if(clientY<=100){ clientY = 100; } // 最小宽度 if(clientY>=300){ clientY = 300; } operaHeight = clientY; // TODO 这里需要取反向 that.$refs.opera.style.height = 400 - clientY +"px"; } document.onmouseup = function () { console.log('当前宽度', operaHeight); document.onmousemove = null; document.onmouseup = null; that.releaseCapture && that.releaseCapture() } } } } } </script> <style scoped> .container { width: 1000px; height: 400px; border: 2px solid #dddddd; display: flex; justify-content: center; } .tab { width: 30px; height: 100%; background-color: #EC8C32; flex-shrink: 0; flex-grow: 0; } .menu { width: 200px; background-color: #AAB6E0; flex-shrink: 0; flex-grow: 0; position: relative; } .content { width: 100%; position: relative; } .opera { width: 100%; height: 200px; position: absolute; bottom: 0; background-color: #F2BE25; } .menu-resize { width: 5px; height: 100%; position: absolute; top: 0; right: 0; cursor: col-resize; } .opera-resize { width: 100%; height: 5px; position: absolute; top: 0; left: 0; cursor: row-resize; } </style>
